Currently logback-feed does not include exception data, although exception markup is included in default feed entry content layout. This is due to incomplete exception data stored by DbAppender in LOGGING_EVENT_EXCEPTION table (see http://jira.qos.ch/browse/LBCLASSIC-170). Until this issue is solved, there is no point in retrieving exception data from the database. You don't even know what is the exception class and message, making the exception data almost pointless.
